nissan xtronic cvt
The XTRONIC CVT is a line of continuously variable transmissions found in many of Nissan's vehicles. Nissan has been working on CVTs for over 20 years, and today's continuously variable transmissions offer excellent fuel economy while still providing good performance. A CVT doesn't need to shift between separate gears like a traditional automatic, instead, they used a steel belt around two pulleys that can smoothly change ratio. Because there are no shifts, accelerating is smooth and constant, and the transmission can keep the engine operating at its ideal speed, whether for power or economy. The XTRONIC CVT also has a wider ratio than most other transmissions, allowing a lower engine speed for more economical cruising. CVTs have fewer parts and are lighter and more efficient than traditional automatics, helping both performance and economy.
